Josie Maran’s argan-oil enterprise just keeps growing, and now she’s turning up the heat. Literally. From skin to hair, she’s currently delivering her trademark oil in self-heating form, designed to restore your dull, tired, overworked locks back to life in just 60 seconds. With bergamot, jojoba, and soybean oil, it’s got all the natural ingredients we love about Josie’s products. Apply one little yet potent ampule (out of the set of five) to wet hair after shampooing and conditioning, and the oil warms your scalp, in a most soothing manner, as it penetrates the hair cuticles. If one minute doesn’t seem like enough, then go for three or even more, then rinse thoroughly. Just use once a week (but you can also use it as often as you like), for maximum moisture, a decrease in split-ends, and all-around healthy gleam. At Sephora for $36.
